 * Hi there guys,
 * I wonder if there is a way to add function only to widgets.
 * I was planning using blueimp lightbox for my images, but since it includes all
   images from the page into the same lightbox I wanted to split images from widgets
   and images from page/post
 * I used this code
 *     ```
       function add_rel_to_gallery($link) {
       return str_replace('<a href=', '<a data-gallery="#blueimp-gallery-test" href=', $link);
       }
       add_filter( 'wp_get_attachment_link', 'add_rel_to_gallery' );
       ```
   
 * to add the data attribute to media links, well that works, but can you add this
   function only to widget areas or only to posts and pages?
